Abstract

UN CIRCUITO CEBADOR PARA LAMPARA DE DESCARGA (1) INCLUYE UN CIRCUITO DE CONTROL DE CORRIENTE (2) QUE TIENE INICIALMENTE UNA BAJA IMPEDANCIA PARA PRODUCIR UNA CORRIENTE INICIAL DE CALENTAMIENTO DE CATODOS EN LA LAMPARA. EL CIRCUITO DE CONTROL DE CORRIENTE (20) ES CONMUTADO EN UNA ALTA CONDICION DE IMPEDANCIA MEDIANTE UN VOLTAJE DE CONTROL APLICADO A SU COMPUERTA (G), ORIGINANDO UN IMPULSO DE CEBADO DE ALTO VOLTAJE A APLICAR A LA LAMPARA (1). UN TRANSISTOR DE EFECTO DE CAMPO (14) ES EFECTIVO PARA MODIFICAR EL VOLTAJE DE CONTROL DE LA COMPUERTA (G) DE FORMA QUE EL CIRCUITO CEBADOR SEA EFECTIVO PARA PRODUCIR UNA SUCESION DE IMPULSOS CEBADORES A LA LAMPARA (1) DURANTE CADA MEDIO CICLO DE UNA FUENTE RECTIFICADA DE CORRIENTE ALTERNA.
